Description

Gegenstand der Erfindung ist eine bçsond.re Ausbildung einer Innenschiene für den Zweck der Behandlung von schenkelhalsnahen Oberschenkelbrüchen. The subject of the invention is a special design of an inner rail for the purpose of treating femoral fractures near the femoral neck.

Erfindungsgemäß weist die in den Knochenkanal einzuführende Schiene an einer Stelle, die sich nach der Einführung in Gegenüberstellung mit dem Schenkelhals befindet, einen hierbei ungefähr in der Achsenrichtung des Schenkelhalses verlaufenden durchgehenden schrägen Kanal auf, und es ist ein zu diesem Kanal passender Schenkelhalsnagel vorgesehen, der nach dem Instellungbringen der Schiene durch den Kanal in den Scheukelhals eingeschlagen werden kann. According to the invention, the splint to be introduced into the bone canal has at a point which, after the introduction, is in juxtaposition with the femoral neck is located, one here running approximately in the axial direction of the femoral neck continuous oblique canal, and it is a femoral neck nail that matches this canal provided that after the splint has been brought into position through the channel in the sternum can be taken.

Auf diese Weise wird trotz der Kürze des oberen Knochenbruchstücl;es eine besonders gute Sicherung der beiden Bruchstücke gegen gegenseitige Knickung und Verdrehung erreicht, so daß der Patient erheblich füller gehfähig wird. In this way, in spite of the shortness of the upper fragment, it becomes a particularly good protection of the two fragments against mutual kinking and twist is achieved so that the patient is able to walk considerably more fully.

Die Zeichnung veranschaulicht die Erfindung an mehreren Ausführungsbeispielen. The drawing illustrates the invention using several exemplary embodiments.

Fig. 1 zeigt einen mit Innenlschiene und Halsuagel versehenen Oberschenkelknochen; Fig. 2 und 3 zeigen je eine Innenschiene mit Halsnagel bei verschiedenen Gestaltungen der Innenschiene; Fig. 4 bis IO zeigen v,erschiedene Schienen-bzw. Nagelquerschnitte. 1 shows a femur provided with an inner splint and neck nail; 2 and 3 each show an inner rail with a neck nail in different designs the inner rail; Fig. 4 to 10 show various rails or rails. Nail cross-sections.

Die Schiene I kann in ihrem oberen, von dem schrägen Kanal 3 durchsetzten Teil massiv sein, während sie im übrigen einen beliebigen geeigneten Querschnitt, etwa nach Fig. 4 bis IO, haben kann. Vorzugsweise wird der Querschnitt kantig gehalten, so daß die Schiene nur in mehreren Längslinien an der Innenfläche der Knochenhöhle anliegt. Besonders zweckentsprechend erscheint eine rechteckige Grundform, wie bei den Querschnitten gemäß Fig. 4 bis 9, die sämtlich in einen rechteckigen Rahmen passen. Bei massiver Ausführung im oberen Teil kann man auf dem übrigen Teil die Gliederung des Querschnittes durch Ausfräsen erzeugen. The rail I can penetrate in its upper, by the inclined channel 3 Part of being solid, while otherwise they have any suitable cross-section, approximately according to Fig. 4 to IO may have. The cross-section is preferably kept angular, so that the splint is only in several longitudinal lines on the inner surface of the bone cavity is present. A rectangular basic shape, as in the cross-sections according to FIGS. 4 to 9, all in a rectangular frame fit. In the case of a massive design in the upper part, you can use the Create structure of the cross-section by milling.

Es kommt auch eine Herstellung aus Profilmaterial, gegebenenfalls auch aus Rohr, z. B. von ovalem Querschnitt in Betracht. In allen Fällen kann man der Schiene mindestens in ihrem gegliederten Teil eine gewisse Elastizität geben. There is also a production from profile material, if necessary also made of pipe, e.g. B. of oval cross-section into consideration. In all cases you can give the splint a certain elasticity, at least in its articulated part.

Der Nagel 2, dessen in den Schenkelhals eindringendem Teil vorzugsweise gleichfalls. wie üblich, ein gegliederter Querschnitt gegeben wird, damit er sich mit dem Schenkelhals besonders gut gegen Verdrehung kuppelt, und der zur Erleichterung seines Einschlagens zwecksmäßig am vorderen Ende mehr oder weniger scharf anzuschleifen ist, wird vorzugsweise am rückwärtigen Ende, mit dem er am Schluß des Einschlagvorganges in der Schiene 1 sitzt. ebenfalls massiv gehalten. The nail 2, whose part penetrating into the femoral neck is preferably same to you. as usual, an articulated cross-section is given to allow it to stand out Couples with the femoral neck particularly well against twisting, and that for relief its impact to be sharpened more or less sharply at the front end is, is preferably at the rear end, with which he is at the end of the wrapping process seated in rail 1. also kept massive.

Man kann auch ihn zunächst im ganzen massiv herstellen und die Gliederung in seinem vor deren Teil durch Fräsen erzeugen. 13ei verhältnismäßig schlanker reclttekiger Grundform, die schon all sich eine gute Kupplung gegen Verdrehen ergibt, ist eine Gliederung unter Umständen entbehrlich.You can also initially massively manufacture it as a whole and the structure generate in his before their part by milling. 13ei relatively slender, more lean Basic shape, which already results in a good coupling against twisting, is one Outline may be unnecessary.
